符合环保要求和盈利的炼钢

Environmental Compliance and Profitable Steelmaking

巴登钢厂多年来采用了环境保护管理理念。致力于减少钢厂向大气、水和土壤中的排放,而且还开发了诸如钢渣、灰尘、氧化铁皮回收作为副产品。这些理念的成功可以看到巴登钢厂的排放值很低,也从副产品回收得到利润。其他诸如减少噪音和检测来自废钢并进入钢铁制造过程中的放射源,这个问题越来越引起钢铁界重视。根据25年来钢铁行业环保的工作经验,巴登钢铁工程公司可以提供这些环保的服务和钢厂环保优化的实施解决方案,以满足环境保护要求,避免昂贵的环保失误。阐述了无需任何降低生产率而减少钢铁企业排放的做法。并介绍了欧洲和世界各地的环保标准。

These concepts deal with the reduction of emissions to air water and soil,but also with the recycling of all by products from steel making like slag,dust,scale and some others.The success of these concepts can be seen by the very low emission values of BSW and also the profit derived from the recycling of by-products.Other ideas have been worked out to minimize noise emissions and to detect radioactive sources which are coming together with the scrap into the steel making process.Operation of a steel plant on a very high productivity level is the basic for high efficiency and low cost.Beside the traditional key figures of a steelmaker we realize all over the world,that the stakeholders can no longer ignore the environmental standards.Especially the off-gas has a huge impact on a ＂clean＂ production.If we look at the present debates,it is clear for the industry that one of the challenges will be the reduction of global greenhouse gases.Badische Stahlwerke GmbH（BSW）,one of the most productive Mini Mills in the world,reached more than 2.2 million tons of good billets in 2008 operating with two conventional 90-ton electric arc furnaces（EAF）.For more than 20 years BSW has been working hard to reduce their gaseous emissions with the focus on particulate matter,organic compounds and also carbon dioxide.This paper shows which level of emissions could be reached without having any disadvantage on productivity and gives an overview of various standards and practices in Europe and worldwide.
